KSJ-026 Cell Setter

KSJ-026 Cell Setter

Ensures accurate alignment and stable probing of PV cells to be measured to achieve high repeatability of measured data.

Overview

Solar Cell Test System

The KOPEL KSJ-026 cell setter employs a self-alignment mechanism that enables high accuracy of ±0.05 mm to ensure stable probing of PV cells to be measured, thus achieving high repeatability of the measured data. It is mounted with two dial gauges to precisely set and control the contact pressure of probe pins. In addition, the KSJ-026 cell setter is provided with a cell vacuum contact function and cell temperature control function to easily reproduce measurement conditions and stabilize the FF values.

The KSJ-026 is incorporated into the KOPEL KSX-1000 high-performance solar cell test system and the KSX-3000H high-efficiency solar cell test system.

Features

  • Supported sizes of the cells to be measured: 50-mm square through 4-, 5-, and 6-inch square
  • Sample plate height of 170 mm, adjustable within pprox.. 30 mm

*1)The thickness of the standard probe bar is 1.5 mm. The probe bar with a thickness of 0.5 mm is available as an option.

*2)The water circulation unit is available as an option.

*3)The vacuum pump is available as an option.

Flexible Unit Configuration to Support Measurement of Various PV Cell Types

The KOPEL KSJ-026 cell setter is available in four configuration types, determined by the electrode position of PV cells to be measured, contact method, and combinations of KOPEL KSM Series probe bars to be mounted on the cell setter. The cell setter can be configured by selecting the probe bars appropriate for the PV cells that you intend to measure. These four configuration types can support a variety of PV cells, ranging from standard silicon PV cells to high-efficiency PV cells such as HIT® as well as back-contact-type PV cells. The four configuration types are as shown below:

Unit Configuration Type BS (Both Sides)
Mounted with top-surface probe bar and bottom-surface probe bar

PV Cells to be Measured: Standard silicon PV cells, HIT® PV cells, and thin-film PV cells

Unit Configuration Type BS

 

Unit Configuration Type SP (Surface/Plate)
Mounted with top-surface probe bar and bottom-surface electrode plate

PV Cells to be Measured: Standard silicon PV cells, HIT® PV cells, and thin-film PV cells

Unit Configuration Type SP

 

Unit Configuration Type EPD (Electrical Potential Distribution)
Mounted with top-surface probe bar for electrical potential distribution and bottom-surface probe plate/bottom-surface electrode plate

PV Cells to be Measured: Standard silicon PV cells, HIT® PV cells, and thin-film PV cells

Unit Configuration Type EPD

 

Unit Configuration Type BC (Back Contact)
Mounted with + probe bar and - probe bar

PV Cells to be Measured: Back contact types (IBC, EWT, MWT)

Unit Configuration Type BC

Customized Configuration

The KOPEL KSJ-026 cell setter is available in customized types, including front-drawer, top opening/closing, and side slide door types, upon request. It can also be integrated into mass-production lines.

Electric Potential Distribution Unit (Option)

KOPEL co-developed a specially designed the electric potential distribution unit with the National Institute of Advanced Industrial Science and Technology (AIST). Unlike the conventional electrometer, this unit enables measurement of the differences in electric potential at multiple points on the cell surface to identify the differences in electric potentials within a cell. The result of this measurement allows enhancement of the accuracy of cell evaluation by supplementing the measured IV characteristics. Also, it can be connected with the PC for automated measurement.
